    (54) Ink jet recording head and ink jet recording apparatus


    (57) In an ink jet recording device having an ink tank integrated type jet recording head (10) and a carriage (20) for mounting the head thereon, good electrical connection is obtained by constituting so that the electrical pad of the connecting terminal (10a) of the recording head (10) and the electrical pad of the connecting terminal (20a) of the carriage (20) are connected to each other while rubbing them one to one. Further, also by specifying the arrangement position of the positioning member, more accurate electrical conduction is effected and also breaking of the positioning member is prevented, thereby providing an ink jet recording device having high reliability in both aspects of recording and durability.
